Ready for The Lying Game?

ABC Family's new summer drama, based on the books by Pretty Little Liars author Sara Shepard, makes its television debut Monday, Aug. 15 at 9 p.m. butThe Hollywood Reporter has the exclusive sneak peek at the second episode, "Being Sutton" -- which marks Heroes star Adrian Pasdar's first appearance as patriarch Alec Rybak. (If you missed the exclusive clip from the premiere, check it out here.)

Pasdar, best known for his portrayal of Nathan Petrelli on the NBC drama (and a stint on ABC's Castle), will play the father of Sutton's best friend Madeline (Alice Greczyn) in The Lying Game, which stars As the World Turns alum Alexandra Chando as separated-at-birth twins Sutton and Emma.

In the second episode, trouble lurks for the twins but they must put all that aside for the annual father-daughter dance.
